Zimmerman Trial: Hearing Over Audio Experts Still Undecided

Sanford, Fla. -- 32 jurors are now past the first round of individual questioning after 4 were added Monday.

Following yesterday's jury selection, a special hearing was resumed to determine whether audio experts will be included in the trial.

The hearing lasted several hours, but ended without a decision.

The frye hearing resumes Wednesday afternoon.

The hearing was originally called on June 8 to determine whether expert testimony on the voices in the 911 call recording could be included as evidence in the trial.

Last night the defense called their third witness.

Jim Wayman, an audio expert, testified there was not sufficient technology to analyze the short samples of screaming found in the background of the tape.

Wayman disagreed with state expert Alan Reich who claimed the voice was that of Trayvon Martin screaming for help.

"So going through this date and hearing the screams, we have much less than a second's worth of data." He said, "That's simply not enough data by anybody's estimation as to who the speaker was, even if we can narrow it down to two speakers."

The hearing will resume wednesday afternoon following jury selection so the state can call a rebuttal witness.
